When the Messiah comes all the nations of the will know why we Jews were chosen by G-d. What a glorious day.
“G‑d then told Moses to inform the Jewish people that eventually the non-Jewish nations would appreciate them and praise them for remaining true to their covenant with G‑d.
[Moses addressed the non-Jews:] “Nations! Praise [G‑d] for His people, [the Jews]!” Deuteronomy 32:43
When the Messianic Redemption occurs, truth will no longer be so easily confused with falsehood. It will become clear to the whole world why G‑d chose the Jews to be His people. Our role as the priests and teachers of humanity will finally be universally acknowledged, and our redeeming contributions to human civilization will be fully appreciated. The nations of the world will then do whatever they can to aid the Jews in their Divine mission of bringing the world to its fullest potential.
Educating the world to appreciate not only G‑d but G‑d’s people is therefore an integral part of preparing the world for the Redemption and hastening it.1 Hitva’aduyot 5748, vol. 1, p. 41
